ABSTRACT

This paper introduces the microcomputer electric appliance remote control principle and working process, mainly uses the highest technology, microprocessor technology to achieve the purpose of remote control. Design mainly adopts the infrared emitting module and the infrared receiving module, and then each of the two modules are programmed. Specify the SCM in electrical remote control in rats. SCM relates to the electric appliance remote control most of the course work. From the view of the development tendency of remote controller for electric appliances, the appearance of single chip microcomputer for electrical remote control of greater advantage, promote a new generation of electric appliance remote control development. The single chip integrated into the electrical remote control, so that the electric appliance remote control the use of more convenient, fast, also be people life simple. With the progress of the times, people living on items are increasingly high requirements, in order to meet the needs of consumers, so the advanced SCM to join the family electric appliance remote controller is in line with the needs of the public. After analyzing and researching on the request of the design, we take several blue print and we selected the best one in the end. The project make use of advanced SCM to realize the remote control. Remote controller we designed can dominate 5 electrical source switches and adjust the brightness of one light.
